Key Features
The ATMOS can be mounted on any adapted high mobility 6×6 or 8×8 truck chassis preferred by the customer. The protected cabin of the ATMOS is designed for a crew of 2-6 personnel, a driver, a commander, and an additional three to four crewmembers along with all personal equipment and small arms. The cabin is equipped with an air conditioning system that is capable of both heating and cooling. The concept behind the ATMOS can be applied to modernization of legacy towed guns, incorporating advanced new technologies like INS, MVR, ballistic computers, C4I, hydraulics and electrical drives.
The ATMOS achieves ranges exceeding 40km with ERFB-BB ammunition and suitable propelling charge. Designed specifically for rapid deployment and operation on difficult terrain, the ATMOS’s shoot-and scoot capabilities are supported by an integrated electronic suite incorporating an INS-based laying system, as well as an automatic loading system that reduces crew effort. The ATMOS can fire all types of qualified 155mm ammunition, projectiles and charges that are in use by NATO and other countries. On board containers store a minimum of 18 rounds, including projectiles, propellants and fuzes.
A fifth generation ATMOS provides advanced fire support for a wide range of missions and is operational in artillery forces around the world.
